ZZYW type self operated differential pressure regulating valveDetailed product description：

ZZZW type self operated micro pressure and differential pressure regulating valve is a type of valve that does not require external energy, uses the energy of the controlled medium itself as a power source, introduces the actuator membrane chamber to generate thrust, and controls the movement of the throttling element to achieve automatic regulation. Mainly used in various industrial furnace gas combustion systems to control the mixing ratio flow of fuel A and B, achieving ideal natural material conditions: used for pressure reduction, stabilization, and relief regulation of sealing oil and various industrial gases such as hydrogen, liquefied gas, oxygen, and nitrogen in hydrogen cooled generator sets; used for gas sealing of various oil, chemical, and liquid storage tanks.
